Not much difference. The pattern is just a formation of code.
Patterns show up holographically. Scalar waves have harmonics that are relative as you move up and down scales. Think c1, v2, c3, etc on a pattern as a simplistic demonstration as to what I am talking about. Then we see patterns in sacred geometry (building matrices of life) and on and on it goes. Code is the thought form "language" and patterns ripple forth from that language. But the patterns and the code are inseparable. The are interlinked. One affects the other. (holographic).
